Effect of chosen substances in food of animal origin in development of lifestyle diseases

This bachelor thesis is devoted to the effect of harmful substances found in animal foods that affect the development of civilization diseases. Fish can contain carcinogenic substances, such as polychlorinated biphenyls (PCBs), polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), pesticides, methylmercury and lead. Higher consumption of red meat and meat products increases the risk of cancer. It can be caused by heme content or substances given into the food during heat treatment or preservative treatment of meat. These compounds include heterocyclic amines (HCA), polycyclic aromatic hydrocarbons (PAHs), N-nitrosocompounds (NOC), nitrates and nitrites. High intake of fat containing saturated fatty acids (SFA) and trans-unsaturated fatty acids (TFA), increases the risk of obesity, cardiovascular diseases, diabetes mellitus and cancer
